Re-watch the Google Hangout: Countdown to Comet ISON

Last Thursday, I joined Senior Editor Rich Talcott, Associate Editor Sarah Scoles, and Discover's Editor at Large Corey Powell for the magazines' first ever Google Hangout discussion. This one covered everything you need to know about Comet ISON (C/2012 S1) before it makes its closest approach to the Sun a week from today. We discussed how comets work, the history of comets (both ancient and recent), what observations of Comet ISON has told observers and scientists so far, how to view the celestial visitor in the coming weeks, and much more.

You can check out our Hangout below, and feel free to ask any additional questions we didn't get to in the comment section at the bottom of this page. And for complete coverage, visit www.Astronomy.com/ISON.
